  <title>sudo: Privilege escalation</title>
  <synopsis>

  <background>
    <p>
    sudo allows a system administrator to give users the ability to run
    commands as other users.
    </p>

  <description>
    <p>
    Harald Koenig discovered that sudo incorrectly handles group
    specifications in Runas_Alias (and related) entries when a group is
    specified in the list (using %group syntax, to allow a user to run
    commands as any member of that group) and the user is already a member
    of that group.
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker could possibly run commands as an arbitrary system
    user (including root).
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All sudo users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-admin/sudo-1.7.0&quot;</code>
  </resolution>
